I have a red spot under each boob. That is extremely itchy on inside and has these different lines almost through out. (photo)

I had breast reduction surgery 2 weeks ago. I have this same occurance of deep red, itchy, swollen spots under each breast. I wasn't sure if it's normal and I'm just over reacting or if something is going on. They have certain spots that are more swollen than others as well. If you look closely at the pictures you can see.
